It's the Porsche 911 Carrera Cup (964) so I think nobody was right so far? but still one Porsche to go ...
Five cars of the nine car Porsche were announced. The rest is four cars. 906or917 956or962 911GT1 919 The Sports prototype can never be removed.
Why would one not produce the 917 if one had the opportunity, one of the very few posters to adorn my bedroom wall as a lad, if it doesn't turn up at some point, it's either not permitted or a missed opportunity.
